Plugin version 1.6.1 crashes on server without renameProvider

I see the following exception stack trace when used with Dhall language server:

java.lang.NullPointerException

I assume that for this server capabilities.getRenameProvider returns null, and the code does not handle that.

Thanks, I just updated the release with the null check
